IVF risks may be overblown
We are often willing to blame technology for our medical misfortunes, but in the case of infertility, the body itself may be the source of trouble. Assisted fertilization technologies that join an egg with sperm in a laboratory, reportedly come with extra risks - including a 31 percent increased risk of infant death and a 26 percent chance of the infant being small for gestational age. Now, a study led by Dr. Liv Bente Romundstad from St. Olavs University Hospital in Norway concludes that the increased risk may be due to the underlying causes of infertility rather than the in vitro fertilization procedure itself. She compared birth weight, size, gestation age, and infant death rate in women who had conceived one child spontaneously and another with IVF assistance with those of women who only conceived using IVF. The findings suggests that since women who conceived both ways had infants with similar good health each time, then the increased risks associated with IVF may be due to factors other than the technological risks.
CAUTIONS: On average the women who conceived with assisted fertilization were older than those who did not use it, so perhaps age, rather than infertility, was the issue.
BOTTOM LINE: "The adverse outcomes [of IVF] seem to be caused by factors leading to or related to infertility rather than the technology," said Romundstad.
